Loading 0% VAT rate on solar panelsThere has been 0% VAT on solar panel purchases since April 2022, meaning solar panels are the cheapest they've ever been. Before becoming Prime Minister, then Chancellor Rishi Sunak said, “A family having a solar panel installed will see tax savings worth over £1,000 and savings on their energy bill of over £300 per year.”The VAT reduction will end April 2027, so if you can afford to get solar panels within the next five years, definitely consider doing so.To find out more, read our complete guide to VAT for solar panels. Who is eligible? Anyone living in England, Scotland, or Wales will pay 0% VAT on solar panels.The cut does not apply to people living in Northern Ireland, though some residents are eligible for a reduced rate of 5% VAT if they are on certain benefits. How to applyYou do not need to apply for 0% VAT on solar panels, since the cut will already be reflected in the quote you are given by your installer. The Smart Export GuaranteeSince 1 January 2020, the Smart Export Guarantee (SEG) has required all large UK energy providers (those with 150,000+ customers) to pay homeowners for any renewable electricity they export to the National Grid.Suppliers now offer as much as 29.3p per kWh, meaning you can earn more than you could from the UK government's now-defunct Export Tariff. The average household in Scotland can now save £142 per year.Of course, this is on top of expected energy bill savings, for an overall saving of £466 per year.To get the full lowdown, check out our detailed guide to the Smart Export Guarantee. Who's eligible? To be eligible for the Smart Export Guarantee, you need to generated electricity through your solar panels.Your solar panel installation also can't exceed a capacity of 5 MW – much higher than wat most domestic households require – and you need to have a export metre or smart metre installed.

FAQs What happened to the Feed-in Tariff? As of March 2019 the Feed-in Tariff is no longer available. It’s been replaced by the Smart Export Guarantee (SEG), which lets homeowners with solar panels sell the excess electricity they produce back to the National Grid, via their energy providers.If you signed up for the Feed-in Tariff scheme before it ended, you will still receive payments for the full duration of your contract (usually 20 years). Is it worth getting solar panels in Scotland? Yes, it's worth getting solar panels in Scotland, because there's still more than enough light throughout the year to power half of your electricity.Even though Scotland sees more cloudy days than much of the rest of the UK, solar panels continue to work under both light and heavy cloud cover.Expect solar panels to become around 24% less efficient under light cloud cover, and around 67% less efficient under heavy cloud cover. How many solar panels does it take to power a house? The average three-bedroom house requires around 10 panels of 350 watts, which will generate approximately 2,370 kilowatt hours (kWh) a year.A smaller house, one to two-bedrooms, will need around six 350-watt panels. A large four-bedroom house will need around 14 of the same panels.
